DOUBLE COOKING-STOVE.

Specification of Letters Patent No. 7,304, dated April 23, 1850.

, the construct-ion of a cooking stove, having two distinctcompartments, with such an arrangement of the fire chamber, grate, andthe flues, that one compartment receives a far higher degree of heatthan the other, thus permitting boiling, roasting, or any kind ofcooking requiring much heat, to be carried'on in one part of the stove,while, at the same time, baking or any kind of delicate cooking,requiring a regular and low degree of heat, may be conducted in theother part. By means of this arrangement,

. in my double cooking stove, a great variety of dishes may be cookedsimultaneously and the culinary operations of a family performed withmuch greater convenience and economy in the consumption of fuel, thanwith the cooking stoves in common use.

To enable others skilled in the art, to understand and use my invention,I will proceed to describe its mode of construction and operation,referring to the annexed drawings, which form a part of thisspecification.

I make my double cooking stove in the usual way, of cast-iron plates orof sheet iron, as desired.

Figure 1 is a front view, having the door of one of the compartmentsopen and the door of the grate partially drawn. Fig. 2 is a verticalsection, exhibiting the stove in operation. Fig. 3 is a top view,showing the issue of the smoke-flue and holes (having covers) forsetting pots, pans, kettles, &c.

The same letters always refer to the same parts.

The form of the stove is not important; it may be square or oblong, thelatter form being, as I think, preferable.

In Fig. 1, A is the front plate or outside casing of the stove; in Figs.2 and 3 B is the top plate; and in Fig. 2 C, O, are the end or sideplates; there are also back and bottom plates which make the frame oroutside body of the stove complete.

The fire-chamber E, and the grate F, are

placed centrally in the body of the stove, running from the front plateA to the back the plates G and H, Fig. 2, form the sides of thefire-chamber and divide the stove into two compartments I, I; the plateH is continued up to and unites with the top plate B, while the plate Gterminates short of the plate 13, and unites with an inside plate J,which forms the top of one of the compartments I, leaving a flue K, thewhole width of the stove, which flue is continued around on the innerside of the stove, and formed by means of the sides L, L, and thebottoms M, M, and the other top J, of the compartments I, I, until it isstopped by the upper part of the plate H, and finds issue in the pipe atN-the course of the flame and smoke therein being indicated by arrows.

The compartments I, I, have doors 0, O, in front, and are also providedwith sliding plates a, a, upon which the pans or dishes are set forcooking.

In Fig. 1, b, is the fire-chamber door, and c, the door of the ash-holeunder the grate F.

The operation and advantages of this arrangement in my double cookingstove, are as follows :The fire being made in the chamber E, the flameand heated smoke and air pass off through the flue K, first around theleft-side compartment I, surrounding it with a highly charged current ofcaloric, which raises the heat in this compartment to a degree muchgreater than in the other, around which the current of caloric passeswhen comparatively eXl1austedan effect which is obvious. The top of thestove over the left side compartment, under which the flame and heatedairdirectly pass, will be exposed also to a powerful heat, and it isaccordingly provided with openings or places to set pots or kettles forboiling, &c., while the top on the other side will be subjected to onlya moderate heat, which for many culinary purposes will be found veryconvenient. Thus it will be seen that boiling, roasting, or other kindof cooking which need a powerful heat may be conducted on one side andin one part of my double cooking stove, while delicate dishes, &c.,requiring a moderate heat, are prepared in the other.

The grate may be so constructed as to burn either wood or coal.
